Dear @pimuzzo

We are really happy to see you contributing to our python SDK, but unfortunately, we cannot accept this pull request.

The SIS API has been deprecated in favor of an S3 compatible one.
This new API is accessible with a standard S3 client at:

• s3.fr-par.scw.cloud
• s3.nl-ams.scw.cloud
